Yuav ua li cas xaiv ib tug connector? Muaj ntau hom connectors. Cov hom muaj xws li kev sib txuas lus interface terminals, xov hlau terminals, hlau-rau-board connectors, thiab board-to-board connectors. Txhua pawg tuaj yeem muab faib ua ob peb pawg, xws li: board-to-board connectors muaj xws li headers thiab poj niam, board-to-board connectors, thiab lwm yam.; hlau-rau-board connectors muaj xws li FPC connectors, IDC sockets, thiab yooj yim horn sockets.
Thaum xaiv ib lub connector, peb yuav tsum xaiv los ntawm cov nram qab no yam.
1, pins, spacing
Tus naj npawb ntawm tus pins thiab qhov sib nrug ntawm tus pins yog lub hauv paus rau kev xaiv cov khoom sib txuas. Tus naj npawb ntawm pins xaiv rau lub connector yog nyob ntawm tus naj npawb ntawm cov teeb liab uas yuav tsum tau txuas. Rau qee qhov sib txuas sib txuas, tus naj npawb ntawm cov pins hauv thaj chaw headers raws li qhia hauv daim duab hauv qab no yuav tsum tsis txhob ntau dhau. Vim hais tias nyob rau hauv cov txheej txheem soldering ntawm lub tshuab muab tso rau, vim yog kub, connector yas yuav rhuab thiab deformed, thiab nyob rau hauv nruab nrab ib feem yuav bulge, uas ua rau tsis muaj tseeb soldering ntawm cov pins. Peb siv hom header thiab poj niam header los ua lub rooj sib tham-rau-board kev sib txuas nyob rau theem pib ntawm kev tshawb fawb thiab kev loj hlob. Raws li qhov tshwm sim, cov pins ntawm tus qauv qauv header tau soldered nyob rau hauv ib cheeb tsam loj. Tom qab hloov mus rau 2 tus pin headers nrog halved pins, tsis muaj cuav soldering.
Niaj hnub no, cov khoom siv hluav taws xob tau dhau los ua me thiab meej dua, thiab tus pin pitch ntawm lub connector kuj tau hloov ntawm 2.54mm mus rau 1.27mm mus rau 0.5mm. Qhov me me ntawm cov hlau lead suab, qhov siab dua qhov yuav tsum tau ua rau cov txheej txheem ntau lawm. Qhov sib nrug ntawm cov hlau lead yuav tsum tau txiav txim siab los ntawm lub tuam txhab' qib kev tsim khoom siv tshuab, dig muag nrhiav qhov sib txawv me me
2, kev ua haujlwm hluav taws xob
Cov khoom siv hluav taws xob ntawm cov khoom txuas feem ntau suav nrog: txwv tam sim no, tiv thaiv kev tiv thaiv, rwb thaiv tsev tsis kam thiab dielectric zog, thiab lwm yam. Thaum txuas lub zog hluav taws xob siab, xyuam xim rau qhov txwv tam sim no ntawm lub connector; Thaum xa cov teeb liab siab xws li LVDS, PCIe, thiab lwm yam, xyuam xim rau kev tiv thaiv kev tiv thaiv. Lub connector yuav tsum muaj qhov sib tiv tauj tsawg thiab tsis tu ncua, feem ntau kaum ntawm mΩ mus rau pua pua mΩ.
3, kev ua haujlwm ib puag ncig
Kev ua haujlwm ib puag ncig ntawm cov khoom txuas feem ntau suav nrog: ua haujlwm kub, av noo, ntsev tsuag, kev co, kev poob siab, thiab lwm yam. Xaiv raws li qhov tshwj xeeb daim ntawv thov ib puag ncig. Yog hais tias daim ntawv thov ib puag ncig yog cov av noo, qhov yuav tsum tau ua rau cov av noo thiab ntsev tsuag ntawm lub connector yog siab los tiv thaiv cov hlau hu ntawm connector los ntawm corroded. Hauv kev tswj hwm kev lag luam, qhov yuav tsum tau ua rau kev tiv thaiv kev vibration thiab kev cuam tshuam kev ua haujlwm ntawm lub connector yog siab, thiaj li tiv thaiv cov connector los ntawm ntog tawm thaum lub sij hawm vibration txheej txheem.
4, mechanical zog
Cov khoom siv hluav taws xob ntawm cov khoom sib txuas muaj xws li kev siv dag zog, cov neeg kho tshuab foolproof, thiab lwm yam. Mechanical foolproof tseem ceeb heev rau lub connector. Thaum nws tau ntxig rov qab, nws yuav ua rau muaj kev puas tsuaj rau lub voj voog!
Insertion quab yuam yog muab faib ua insertion force thiab sib cais quab yuam. Cov txheej txheem muaj feem cuam tshuam tau hais tias muaj zog ntxig loj thiab lub zog sib cais me me. Los ntawm kev xav ntawm kev siv, lub zog ntxig yuav tsum me me thiab lub zog sib cais yuav tsum loj. Kev sib cais me me yuav txo qis kev ntseeg tau ntawm kev sib cuag, tab sis rau cov khoom sib txuas uas feem ntau yuav tsum tau ntsaws thiab tshem tawm, kev sib cais quab yuam ntau dhau yuav ua rau qhov nyuaj ntawm kev tshem tawm thiab txo cov neeg kho tshuab lub neej.
Txhawm rau txo qhov kev sib cais quab yuam ntawm cov khoom sib txuas thiab ua kom yooj yim rau cov neeg siv ntsaws thiab tshem tawm lub rooj tsav xwm adapter, cov neeg tsim khoom txuas tau ua ntau yam kev sim, thiab thaum kawg pom lub teeb ci ntawm txoj kev tshawb nrhiav.
Connectors, uas feem ntau hu ua connectors los ntawm engineers, yog siv los txuas ob lub Circuit Court boards los yog cov khoom siv hluav taws xob kom ua tiav lub zog lossis teeb liab. Los ntawm kev sib txuas, koj tuaj yeem ua rau lub voj voog module
Simplify cov txheej txheem sib dhos ntawm cov khoom siv hluav taws xob thiab ua kom cov khoom yooj yim los tswj thiab txhim kho. Rau modular circuits, cov chaw tsim tshuaj paus connector qhia tias kev xaiv ntawm lub connector plays lub luag hauj lwm txiav txim.
